Biography
Thomas Walker Gilmer was born in Albemarle County, Virginia in 1802, and he practiced law in Charlottesville before serving in the House of Delegates from 1829 to 1836 and from 1839 to 1840. He went on to serve as Governor from 1840 to 1841, opposing the extradition of slave stealers. In 1840, he was elected to the US Congress as a Whig, but he became a "Tyler Democrat" in 1842 due to his support for John Tyler's presidency. He was an avid supporter of the annexation of the Republic of Texas, and he was appointed Secretary of the Navy in February 1844. However, on 28 February 1844, he was one of several notables killed in the USS Princeton disaster, when a bow gun exploded while firing a salute to Mount Vernon.
